test case to compare full CPUID dump for unexpected ABI changes

This adds a new test function to the cpuid.py test module, where the
CPUID data exposed by QEMU is compared with a full CPUID dump extracted
previously.

The new test code ensures that there are no ABI changes for a given
machine-type + CPU model combination, between QEMU versions.

The reference dumps were generated using the build-qemu-and-dump-cpus,
and copied using the copy-ref-dumps script.

There are some known QEMU bugs and past ABI changes that require
ignoring some differences. Those cases handled as rules that set
ignore_cpuid_leaves on qemu_cpu.cfg.

Call env_process.preprocess_vm(test, params, env, vm_name) to create vm could skip this issue.

qemu_devices: Fix network creation problem with RHEL5

We were assembling the network device cmd line for RHEL5
QEMU incorrectly, post the qemu_devices work.

 bad cmdline:
     -net id=idprh29y,macaddr=9a:49:4a:4b:4c:4d,model=virtio,type=nic,vlan=0  \
     -net tap,vlan=0,fd=24  \

 good cmdline:
     -net nic,vlan=0,model=virtio,macaddr='9a:21:22:23:24:25',id='idxlzqAk' \
     -net tap,vlan=0,fd=24 \

Fix this by making the 'nic' param of the custom QDevice
NO_STRING_EQUAL, and making sure such params come first before others.
